Tubo-ovarian abscess with endometrial cyst probably infected by Campylobacter fetus: Two cases

J Obstet Gynaecol Res. 2016 Aug;42(8):1052-7. doi: 10.1111/jog.13004. Epub 2016 Apr 14.


Campylobacter fetus often causes systemic infection in immunocompromised or older patients, and prenatal infection, but Campylobacter has rarely been reported as a cause of adnexitis in healthy young women. Here we report two cases of endometriotic cysts infected by C. fetus for the first time. In case 1, a 28-year-old woman with a left adnexal cyst was hospitalized for left tubo-ovarian abscess and underwent left salpingo-oophorectomy. In case 2, a 22-year-old woman with a right adnexal cyst was hospitalized for a bilateral tubo-ovarian abscess and underwent right salpingo-oophorectomy and left salpingectomy. In both cases, C. fetus was detected on culture, and histopathology indicated a purulent endometriotic cyst. The present findings suggest that endometriotic cyst can be a focus of C. fetus infection.
